Shadow Skill: Kurudaryuu Kousatsuhou no Himitsu

Gau Ban trains under his adoptive sister, the warrior Elle Ragu, hoping to approach the strength of Scarface, a fighter renowned for defeating thousands of opponents. His path toward martial mastery soon leads beyond ordinary practice.

Intruders attack the castle in pursuit of a secret box, drawing Gau into a confrontation connected to the mysteries of the Kurudan fighting style. The struggle tests both his training and his ability to face warriors with far greater experience.
